Do you feel it in the steering wheel or your butt? If steering wheel it will be in the front. In you butt, engine back.

U joints possible but usually they will show through out the range. Check for bad tire, shifted belt. Bearings usually do not cause vibration unless they have really gone bad and you will hear them then. Check half shafts and installation.

Rear bearings and rear you can get a good idea of any bearings by listening to them with your stethoscope. Long screw driver will work, as will a length of fuel line.

That's the thing... I feel it in both. It's literally shaking the entire chassis--pretty sure it's from the rear though.
